So after some testing in PvP.

Viper does not even have good sustained damage compared to a Glass Cannon Machinist that has a Range advantage and a HARD CC and a instant kill LB under 50% HP if timed right that ALSO recharges prety fast....
So this also can be added to the list...

Viper either needs an entire PvP kit redesign or some CRAZY levels of Buffs at this point.
its not good at anything and lacks in everything lol
